CERATOPHYLLACEAE 
CERATOPHYLLUM Linnaeus 
Ceratophyllum submersum Llanos Frag. Pl. Filip. (1851) 105 (Cerato- 
phillum); F.-Vill. & Naves in Blanco Fl. Filip. ed. 3, 4* (1880) 81, 
non ? Linn.=CERATOPHYLLUM DEMERSUM Linn. 
From the material available I am inclined to refer the Philip- 
pine form to Ceratophyllum demersum Linn. The species is 
common in shallow lakes and in slow streams in the Philippines.

RANUNCULACEAE 
NARAVELIA de Candolle 
Atragene zeylanica Blanco Fi. Filip. (1837) 461; ed. 2 (1845) 321; ed. 3, 
2 (1878) 231, non Linn. =NARAVELIA LAURIFOLIA Wall. - 
This was considered by Fernandez-Villar to be in part Nara- 
velia laurifolia Wall. and N. zeylaniea DC., but the latter species 
does not extend to the Philippines. I previously considered 
that the description seemed to include Naravelia laurifolia DC. 
and Clematis gouriana Roxb., but the description certainly does 
not apply in any respect to the latter; I am now of the opinion 
that Blanco’s description covers a single species, and that is 
Naravelia laurifolia Wall., a species widely distributed in the 
Philippines at low and medium altitudes, but of local occurence. 
Illustrative specimen from Bosoboso, Rizal Province, Luzon, 
March, 1915 (Merrill: Species Blancoanae No, 885). 
Atragene lobata Llanos Frag. Pl. Filip. (1851) 73 (sp. nov.); F.-Vill. & 
Naves in Blanco FI. Filip. ed. 3, 4* (1880) 57—=NARAVELIA LOBATA 
(Llanos) comb, nov. (Naravelia leheri Merr. & Rolfe}. 
. This species was reduced by Fernandez-Villar to Naravelia 
zeylanica DC., a species that does not extend to the Philippines. 
It is certainly the form more recently described by myself and 
Mr. Rolfe as Navavelia loheri. The species is of local occurrence 
at low altitudes in the settled areas in the provinces near Manila. 
Illustrative specimen (a topotype) from Calumpit, Bulacan © 
Province, Luzon, January, 1915, growing in thickets and hedges, 
and known as parapit hanguin, the name cited by Llanos for 
Atragene lobata (Merrill: Species Blancoanae No. 656).
